Overview
The TAS5722LRSMT is a digital input mono Class-D audio amplifier manufactured by Texas Instruments. It delivers 15 W of continuous output power into a 4 Ω load with 0.02% THD+N at PVDD = 16.5 V. The device operates on a single supply voltage ranging from 4.5 V to 17 V. It features high efficiency exceeding 90%, eliminating the need for external heat sinks. The component is housed in a 32-pin VQFN package (4x4 mm) and supports an operating temperature range from -25°C to +85°C.
Feature Summary
- Digital input interface for direct connection to digital audio sources
- High-efficiency Class-D operation exceeding 90% to minimize thermal management requirements
- Integrated current sensing capability for speaker protection and diagnostics
Applications
- Portable multimedia devices requiring compact audio solutions
- Smart home speakers and voice assistants
- Automotive infotainment systems
Procurement Notes
Verify the specific suffix 'RSM' indicates the VQFN-32 package variant. Confirm the 'T' suffix denotes tape-and-reel packaging suitable for automated assembly. Ensure compatibility with the required digital audio interface protocol before integration. Check humidity sensitivity levels for proper storage and handling procedures during manufacturing.
Selection Notes
Select this model when a mono channel configuration is sufficient for the application. Choose based on the requirement for digital inputs rather than analog signals. Consider the 15 W power rating relative to the connected speaker impedance. Evaluate the 4.5 V to 17 V supply range against the system's available power rails.
Part Context
This component belongs to the TAS5722L series of digital input mono Class-D amplifiers. It shares architectural similarities with other members like the TAS5720L but offers distinct power and voltage specifications. The series is designed for space-constrained applications where thermal performance and audio fidelity are critical priorities.
Replacement Considerations
The TAS5722LRSMR is a reel-packaged version of the same functional device. Verify pinout compatibility if substituting with other TAS572x family members.
